STEAM-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 763,079, dated June 21,1904.

A li ati n fil d January 19, 1904. Serial No. 189,751, (No model.)

To a, w/wm it may concern:

Be it known that 1, CHARLES SYKORA, a citi- Zen of the United States,residing at Amo, in the county of Cottonwood and State of Minnesota,have invented new and useful Improvements in Steam-Generators, of whichthe following is a specification.

My invention pertains to steam-generators; and it has for its object toprovide a steamgenerator designed more particularly for burning strawand similar fuel and one which is constructed with a view of beingexpeditiously cleared of soot and other collective products ofcombustion and is calculated to utilize the flames and heated gases tothe best advantage for heating the feed-water precedent to the passageof the same into the boiler proper.

With the foregoing in mind the invention will be fully understood fromthe following description and claims when taken in connection with theaccompanying drawing, forming part of this specification, in which thefigure is a view, partly in longitudinal vertical section and partly inside elevation, of the generator constituting the preferred embodimentof my invention.

Referring by letter to the said drawing, A is the boiler proper of mynovel generator, which is provided with the usual steam-dome a and isalso provided with the usual waterholding depending portion 6,surrounding a combustion-chamber B.

C is a baffle-plate disposed in the combustionchamber about midway theheight thereof.

D is a smoke-box arranged at the forward end of the boiler proper andhaving the usual uptake or stack 0.

E E are smoke-fines connecting the portion of thecombustion-chamber Babove the baffleplate C and the smoke-box D, and F is a door controllinganopening G in the rear wall of the upper portion of, thecombustion-chamber B.

In virtue of the construction thus far described it will be observedthat the fines E may be very quickly and easily cleared of collectedsoot and other products of combustion .by introducing a suitable scraperthrough the opening G and forcing such products of combustion into thesmoke-box D, from whence the same may be readily removed through theusual door. (Not shown.)

In addition to the baffle-plate C the combustion-chamber B is providedwith a spout H,

having an inwardly opening gate valve 1,

which is calculated to permit of the introduction of straw or'similarfuel into the chamber and prevent the escape of flames and otherproducts of combustion therefrom. The combustion-chamber is alsoprovided with a deadplate J, disposed below the spout H, and a grate K,arranged in front of said dead-plate.

The dead-plate and the grate are arranged over the usual ash-pit L,which is provided on its front and rearjwalls with suitable dampers c,as illustrated.

Surrounding the smoke-box D is a jacket M, separate from the remainderof the boiler, into which the feed-water of the boiler is injected orotherwise forced.- The said jacket heat the water in the boiler properthe remaining heat of said flames and gases will be utilized to the bestadvantage to raise the temperature of the water in the jacket, and hencethe water will enter the boiler proper in a heated state and be quicklyconverted into steam therein.

The arrangement of the jacket M separate from the boiler A isadvantageous, since the water is heated in the jacket to a considerableextent precedent to being supplied to the boiler, while the arrangementof the pipe N on the exterior is advantageous because of the facilitywith which said pipe may be removed and cleared of collected scale andthe like and when necessary replaced with a new pipe.

As will be readily observed by reference to the drawing, the lowerportion of the jacket M is isolated from the boiler A, and the onlyconnection between said jacket and boiler is the pipe N, connected atits opposite ends to the tops of the jacket and boiler and having itsend which communicates with the jacket disposed in a horizontal planeabove that of its other end. From this it follows that all of the watermay be removed from the boiler A for any purpose and yet the jacket Mwill remain full'of water; also, that when the generator is used in atraction-engine there is no danger of the jacket M getting dry when theengine is traveling uphill.

Notwithstanding the advantages of my novel generator as pointed out inthe foregoing it will be appreciated that the same is simple andpractical in construction and may be built quite as cheaply as theordinary generators extant. It will also be noticed that the generatormay be either stationary or portable without involving a departure fromthe scope of my invention.

Having described my invention, what I claim, and desire to secure byLetters Patent,

1. The herein-described steam-generator comprising a boiler, acombustion-chamber disposed at the rear of the boiler and having abaflie-plate, a dead-plate and a grate, a feedspout communicating withthe combustionchamber above the dead-plate and having aninwardly-opening gate-valve, a smoke-box arranged in front of theboiler, a door in the rear wall of the combustion-chamber in a planeabove the baffle-plate, smoke-flues arranged in the boiler andconnecting the upper portion of the combustion-chamber and thesmoke-box, a water-jacket separate from the boiler, surrounding thesmoke-box and adapted to receive feed-water, and an exterior pipe Nconnecting the upper portion of the waterjacket and the upper portion ofthe boiler.

2. A steam-generator comprising a boiler, a combustion-chamber disposedat the rear of the boiler, a smoke-box arranged in front of the boiler,one or more smoke-fines extending through the boiler and between thecombustion-chamber and the smoke-box, a waterjacket surrounding thesmoke-box and adapted to receive feed-water; the lower portion of saidjacket being isolated from the boiler, and a conduit connecting the topsof the boiler and water jacket; the end of said conduit whichcommunicates with the water-jacket being disposed in a horizontal planeabove the end of the conduit which communicates with the boiler.

In testimony whereof I'have hereunto set my hand in presence of twosubscribing witnesses.
